Maintenance The only maintenance required on the HSD is replacing the tri-clamp gasket periodically. While the frequency of replacement will depend on installed operating conditions (e.g., products used, cleaning chemicals, temperatures), it is recommended to replace the gasket at least annually. Clamps can also be replaced depending on wear condition of the clamp. If the HSD body or deflector becomes damaged to the point beyond use, replace the entire assembly. Troubleshooting Table 2: Troubleshooting Problems Solutions
1. Make sure that the tank vent port is adequately sized for the application. 2. Disassemble the HSD and make sure that nothing is blocking the area between the deflector plate and the body. 1. Check operating conditions of the spray device(s) and make sure that operation is not higher than recommended flow and pressure. 2. Note that the HSD will stop many direct spray(s) but will not block hot or moist air from exiting the tank; the solution may just be humid air and/or air with entrapped solution (this is more common during a tank fill step when the air in the tank is displaced by the incoming solution).
